I know this is really off topic but I have a lot of respect for the depth of knowledge here and also know that there are some aircraft enthusiast/maint people here so I would appreciate some recommendations.
I have a recurring problem with the exhaust pipe tabs on my Maule aircraft. They (tabs) keep breaking at the weld on the pipe, probably because the stainless pipe is too thin to hold up under the stress and the connection is too rigid. I'm hoping I can get some constructive feedback on how to solve this problem. The pipes have to be able to move some but need to be secured at the lower point.
This is what the broken tab looks like:
This is an old pipe and clamp that I have from previous break, it has been welded/ repaired.
The lower end of the pipe just needs some support, it's not a structural issue and the top end of the pipe is pinned at the exhaust connection and secured with a clamp but is designed to allow for some movement.
I'm open to any suggestions or dialogue and can add additional pics if helpful. Unfortunately, the hangar is not the most comfortable place these days with temps going below 32 deg.
